For a stone or a pebble the best method is to use a graduated cylinder and the displacement method. Fill the jar with water to a level so that the pebble can be completely submerged. Read of the volume. Then insert the stone or pebble into the cylinder and read off the new volume. The difference between the two will be the required volume.
However, for a rock the equipment needs to be scaled up and graduated cylinders don't usually come that big. So you will need a bucket or something in which the rock can fit and a tray or large enough container to catch the spill from the bucket (see next paragraph).
Put the bucket in the tray. Fill the bucket with water - full to the top. Then very gently lower the stone into the bucket, catching all the spilling water in the tray. Measure the water in the tray using whatever measuring equipment you can get hold of. That is the volume of the rock.

What did Archimedes find?
He discovered the method to calculate the volume of a irregular object (rock).
What is the method that you use to find the volume of a pebble?
put some water in a measuring cylinder, take the reading and then place the pebble in the water and take over the reading.Then you minus the two values to get the volume of the pebble\rock
How do you find mass of a rock by its density?
Determine its volume by how much water it displaces, then divide mass by volume
How would you find the volume of an irregular shaped object like a rock?
You would measure the length width and heighth. Then you would multiply them all together. <><><> A better means would be to have a container that the rock will fit in, and fill it full of water. Place the rock in the container, which will overflow. Then remove the rock, and measure the volume of water you have to pour into the container to make it full again. The volume of the water will equal the volume that was displaced by the rock.
What is the density of a rock if the volume is 5ml?
You need the mass and volume to calculate the density
How do you find the volume of an odd size rock?
The volume of an odd size rock can be obtained through methods like displacement method.
What did Archimedes find?
He discovered the method to calculate the volume of a irregular object (rock).
How can you find the density of a rock or key?
Find the mass using a scale. Find the volume by the water displacement method. Divide mass by volume and that equals density.
How would you find the volume of an irregularly shaped object such as rock?
You can find the volume of an irregularly shaped object, like a rock, by using the water displacement method. Submerge the object in a known volume of water in a container. Measure the increase in water level, which equals the volume of the rock.
Describe a method that the student could use to find the volume of this rock?
The student can find the volume of the rock by using the water displacement method. First, fill a container with water and note the water level. Then, submerge the rock in the water and measure the new water level. The difference in water levels gives the volume of the rock.
How would you find the density of an irregularly shaped object such as a rock?
To find the density of an irregularly shaped object like a rock, you can use the water displacement method. First, measure the volume of water displaced when the rock is submerged in a known volume of water. Then, divide the mass of the rock by the volume of water displaced to calculate the density.
How can you find the volume of a rock that is too big to fit into a graduated cylinder?
One way to find the volume of a large rock is to use the water displacement method. Fill a container with a known volume of water, then carefully lower the rock into the water. Measure the change in water level to determine the volume of the rock.
Is multiplying the length x width x height a good method to find the volume of a rock?
No. I say this because a rock is usually circular and not a perfect figure. :-)
How would you determined the volume of the rock?
For complex shapes finding the volume is quite difficult. You could do it one of three ways: Simplify the rock's shape, say as a sphere, then use 4/3(pi)(radius^3) to find the volume. Or you could integrate the surface area. I suggest you look up how to do this, since it cannot be easy taught. If you are looking for a simple answer, stick with the first method. Another method is, if you know the density of the rock you can weigh it and find the volume using: mass/density = volume
Best way to measure the vplume of irregularly sharpe rock?
To measure the volume of irregularly shaped rocks, you can use the water displacement method. Submerge the rock in a container of water and measure the change in water volume as the rock displaces the water. The difference in water volume before and after submerging the rock will give you the volume of the rock.
How do you find out the volume of a rock?
Height times width times length equals the volume of the rock.
How do I find the volume of a rock?
Irregularly shaped objects have no formula for finding the volume. So, to find the volume of a rock, one method is to measure how much water the rock displaces. You simply need some sort of container that measures the volume of liquids and you need some water. The container should be large enough to put the rock in. First, fill the container to a certain volume, noting what that volume is and making sure that enough water is used to completely cover the rock when you put the rock in the container. Next place the rock into the container and measure the new volume indicated by the water. Subtract this new volume with the old volume, and the answer will be the volume of the rock. Another method is to use the rock's mass and density to calculate the volume. This can be tougher because you might not know what type of rock you have and many rocks are composites of different types of rocks. Some internet websites give the densities of different rocks. The website http://www.earthsci.unimelb.edu.au/ES304/MODULES/GRAV/NOTES/densities.html gives some simple densities. But if you have all this information, the volume can be determined by measuring the mass of the rock and dividing that number by the density.
